Now supports GoPro HERO13 Black GPS9 metadata with enhanced map‑synchronized playback. When you drag and drop an MP4 or LRV file containing GPS information into this app, playback begins with synchronized video frames and a clearly visualized travel route on the map. This update adds full support for GPS9 metadata found in newer GoPro devices, and improves the map window to show synchronization status more intuitively. The free version of this app has functional limitations. The “Next Playback” feature is not available, and the app cannot load new video files after 10 minutes of playback. These restrictions can be removed by purchasing the optional in‑app add‑on.

• Play MP4 and LRV video files containing GPS5 or GPS9 metadata. • Display the travel route on an OpenStreetMap view. • Synchronize the map position with video playback in real time. • Show a clearly visualized synchronization indicator in the map window. • Update the current location marker as the video progresses. • Freely arrange the video and map windows on the screen. • Configure master–slave behavior between the video and map windows. • The free version does not include the “Next Playback” feature. • The free version cannot load new video files after 10 minutes of playback. • These limitations can be removed by purchasing the optional in‑app add‑on.
